(a) Go Yamashita has a paper in preparation titled ‘A proof of abc conjecture after Mochizuki’, and he also is in the middle of a string of lectures on that topic : 18 hours of talks at RIMS last september titled ‘Inter-universal Teichmuller theory and its Diophantine consequences’, and two further weeks of lectures (68.5 hours in total) next march at a RIMS workshop titled ‘On the verification and further development of inter-universal Teichmuller theory’ ;
(b) Chung Pang Mok is in the process of giving an introductory talk to some of Mochizuki’s ideas at several places : a few weeks ago at MSRI and at UC Santa Cruz, and in the coming weeks at U British Columbia, and at Duke.
